Be it known that L'Gns'rAvUs E. Sriinnss, United States, and a residentof the city of New York, inthe county f New York andStat'e of New York,have invented certain new and usefulv Improvements in Loose-Leaf Files,of Whichthev following is a specification.

The present invention rel atesto improve? ments in devices for filing ortemporarily The main objectof the-invention is to provide Va simpledevice of vthe character' mentioned, which is capableof extension, to

`^ "increase the capacity ofthe file.

Another object 'of' the invention is to Y produce a filepth'atl can beplaced-'vcrtically Y y y A further -into azcabinet and handled thereinconven-v I head 22and the portions of the'sides 21 ad-' Vjacei'itthereto areprovided with inwardly iently.

ectionsy similar'to the ,one shown in Fig. S Fig. 13` -is aperspectiveview, showing the manner of mounting the clamping plate ofthe file on one of the extensible' elements thereof; i f

In the drawings, the numeral 2() indicates kthe baseer back plate oftheimproved file, Y made .of any suitable material, suchas jforinstancametal. This plate is yprovided with sides 21 anda head 22,connecting-thesaid extend, pref- Vbody of the l sides. "These sides andheady erably, at right langles to the plate-.20. When ofmetal, the sidesand head are made, preferably, integral with the plate, as clearlyappears from thedrawings, but, when -made lof wood, they' are, prefer-.ably,`1nade of separate pieces and attached to the'pla'te lin anysuitable manner. *The .extending flanges 22 and 21', respectively, saidflanges being disposedVV in al plane parallel to that of the'v plate20., The base plate, with-its sidesandhead, constitutes a Vshallow tray,thatA` is open at. its ,end 23, to

of sai'dextension members being formed, preferably, of a metal strip.Each eXtension lmember comprises abody portion 26,

that is' disposed parallel to the head'22 ofV the plate 20, and providedatL its ends with short legs 27, that arefbent atrightjanglesto and iextend in* parallelV relation )to the sides 21, above mentioned.

\ The extension member 24 is embraced, ias it were, by the'V sides andhead of the plate 20,'

andthe vextension member 25 vby the extenf sioirv member 24. Theextension `member l 24 with Athe elements inother positions; and;`

denoted by the numerals ves therein to 'be easily A is `substantiallyZ-shaped cross-section, l its outwardly bent -flange 2 8 ,being inalinement with ,andcoperating, ina manner hereinafter tobe described,with the" flange 22 of i the head 22, and its inwardlybent l,ia'nge 29'vcoperatingjv with the outwardly A. bent vharige 3Q ofy theektensionlmember'25, the fr latter being' substantiallyL-shaped. PThe flanges 28,I29 vand 30 of the two extension i members extend, saine, and serve,

above referred to,to prevent a dis` preferably, all around the incoperation 'with the Vi'ormed in each short leg of the extension membe`24, in proximity otits flange 29,

" formed an opening 35,

and these apertures positions. In a similar manner are formed in eachshort leg 27 of the extension member 25 two apertures, indicated'at 33and 34, the apertures Vand in the tworlegs beingl Vin alinenient, and soalso theapertures 34 there in. In each side 21 oli the base plate 20 isthe two openings be- Through each of these openings extends` a headedstud 36, which is slidably disposed iii a tubular projection 37 onthe-outer face of the Vrespective side 21.V Each stud is under theaction o i' a.V

spring' 38, one end of said spring bearing against a cap 39, closing theprojection, and the other end being attached in any `suitable manner to.the stud'.` The heads 40 of the studs are larger in diameter than theprojections 37, and bear` against the caps on the the head 40 of each'adjacent outer face of the From this itappears that stud is spaced fromthe" respective side. 21. this arrangement willV appear hereinafter. Thestuds areeach of a length` rso asto be projected through theapertures-in the adjacent two short legs of the 'extension members, tohold the latter in the desired position ,in relation to each other andtothe base plate 20.

To the free edge of the body the extension member 25 clamping' body 41.This body may be of any suitable construction, the one herein desaidprojections.V

The purpose oli' .portion 26 ot' .e scribed being shownionly forpurposes' of illustration. l It comprisesa yokeshaped wire piece, theends of which are coiled around `ay spindle 42, .that is carried by theextension member 25, the free ends 43 of the coils bearing 4against'thesaid extension member.v

The Y clamping member .is made ofY spring wire, the spring Vcoils havinga tendencyY to force the tree end 41 ofthe clamping body toward theplate 20 o the hold an index plate 45, thelatte` beingY .To the outerplate 20 is attached, in any suitable manner, an index holder 44 of `anysuitable' construction, whichis adapted to detachably;

made ofiany suitablev material and is insertible.; into. andl removablefrom" thc said as close as possible to the head 22 ot 32 are also inalining y leatis placed within the t therein (Fig. 11).

is att-ached a face of the head 22 of the holder.Y On the index platemay be provided Van identification mark 45'., indicating the contentsvofthe file. Y

The operation loif this'device is as follows: Then the file is lirstbeing .assembled, the studs 36 are seated in the apertures 82 and 84 intheextension inembers'24 Vand 25, respectively. Both extension membersare thus held within the tray-shaped file, their` heights correspondingsubstantially to those ofthe siles 21 and head 22 on the plate 20 (Figs.2 to 8, inclusiveh` To insert a Yleaf into thelle, theclamping body 41thereof is swung around thespindle 42 against the action of. its springcoils, after which-the 'ay andthe clamping body released, wherebythelatter presses aOainst the leaf, holding itv within the tray.

1f itis intended to increase the capacity or' the file, the studsBG aredisengaged from the apertures 34'in the extension member 25, and thelatter shifted until its apertures 323 are Ain registering positionswith the said studs, after which the said studs are seated in thelast-named' apertures (Fig, 9). 1t a-further extension is-necessary, thestuds 'are disengaged from vthe* extension membei' 25, in which case thecooperating iianges 29 and 8() of the extension nien bers 24 and 25,respectively, limit the extent of the outward movement ozt theextension-member (Fig. 10). Still'i'urther extension may be obtained bydisengaging the studs 3611'0111 thefapertures 32 'n the `extensionrmember 24 and seating'the saine in the Vapertures 31 The largestextension is obtained 'when'the studs 361aredisengaged from theextension member 24, and the lia-nge 28 on the last-named extensionmeniber is permitted to englgageA with ther Hangs 21 on the sides 21 ofthefplate 2O (Fig, 12).

By these operations, tlie heights oit the sides 21v and headf 22 of theVplate 2O are increased, so that the l'e is ada ated. tohold af greaternumber ci leaves. Y Y

It is obvious that, while herein two cx` tension members have been`shown, any other suitable number may beeinployed. -Furtier- Y more,attention is called to vthe factv tl'iat, while herein a speciicmeansl'ias been4 dis. closed for `positioning the extension meinbers inrelation to the sides and hea-d of thel plate 2O of the file',- anyother construction may be; made use of-without departing ironi theinvention, which lies'inainly in the provision of means height of saidsid'esand head, in confibina-v tion with a clampingr member carriedbyoiieV of fthe extensiony members.V [It should 'be ioted also that,while herein in each short- 12o tor` increasing, at will, the

leg'of'the extension meinbers'two apertures fhave been 4vs'hown,1z' inyother'suitable number maybe provided therein.
